To all whom it mayooncern I Be itknown that I, ROBERT ZAHN, a subject of the German Emperor, residing at in Vogtland, in the Kingdom of Saxony, Germany, have inventedlcertain new and useful Improvements in Embroidering-Machines, of which the following a specification.

high relief, as, for instance, a button-shaped part, or. embroidery work, two methods have been hitherto used. One consists in that the part'which is to be the high relief is produced by a great number of intersecting and overlapping stitches whereby a sort of padding is obtained,- which is then covered by smooth and par- .To produce allelflat stitches. The other method which is less tediousthan the former, consists in that a soft inlay or filling of the desired shape, area and thickness is placed at the point where thcrelief is desired, then this filling first by a few stitches is fastened to the fabric and finally its entire surface, is

machines of the sizes now generally used. l

covered by a great number of smooth and parallel flat stitches. The first named method is disadvantageous for machine embroidery and particularly for such produced by automatic machines, because in view of the considerably high expense incurred by the installation of such automatic machines, the loss of time necessary tomake the in numerable stitches renders the work not economical and this so much more since the consumption of great quantities of thread requires a frequent exchange of the shuttles, during which periods themachine must be at rest. The second method referred to' is comparatively simpler and requiresrless thread. The insertion of the inlay or fill ing hitherto has been done by hand. :With machines that are equipped with about a thousand needles, the attendants would have to apply byhand a filling to each needle, and during this workthe machine would have to be at rest. It is therefore obvious that even the second method would be inefficient for It is the object of this invention to pro:

. vide means whereby the second method may be efficiently utilized for machine embroidery. c j I My invention will be more easily understood by reference to the accompanying drawing, which more or less diagrammati cally illustrates the construction and operat1on of my new device. i

In the drawing, in which similar reference, charactersdenote corresponding parts, so much of the embroidering machine is shown as isnecessary to fully understand the operation 'of my new'device,.Figure 1 k I showing a side view of the. automatic em broidering machine equipped with-mynew' device; Fig. 2 a plan view ofthe device;

. Figs. 3 and'3 similar views asFig. 1 of a modified constru-ctionof the device in two diiferent positions andFig. dapartial' plan view of the modifieddevice; v c In. the drawing let denote the em .broidering surface or the fabric. i

a 7, and 7 are theupper and lower rowsof needles .fiXedto the needle bars? which are l operated in: well known manner by suitable 7 means (not shown). Arranged above and i crosswiseto the needles (see Fig. 2) is a spindle 18 which is suitably supported in bearings 8, fixed bell crank levers 3, 3' arms 3 are somewhat curved'in the manner shown in Fig. .1. The free ends of the arms parallel to the shaft or spindle 8 and which and tothejends of which are ,ofwhich the' 3 are con'nectedby a bar or rail 2 extending hold the inlay or filling pieces 1' which may g be flat, ring shaped or otherwise, just as required. There is one receptacle for each needle.

of the embroiderlng machine are connected by links or rods 4: and through the medium of a rod 5 areoperated from the jacquard 1 mechanism which is indicated in the drawng by 16. The jacquard mechanism, according to the jacquard card,(not shown), and in well. known manner, causes the arms 3 through the medium of the rod 5 and link 4 to swing from the dotted line position to the full line position and back (Fig. 1) so that the receptacles will describe circular paths and during their downward movement will be brought into the range of the stitching needles 7 The receptacles 1 ing bottom 1", which terminates into ,a narrow downwardly projecting chamber 1 which is open at its bottomat 1 and having -Tlie other arms 3 of the bell crank levers for the upper and lower needle rows are formedwith a slantopen slanting in its center recessesl When the levers .3, swing downwardly and the receptacles 1 are brought into the range of the needles 7 the lowermost of the inlay pieces, which are stored on top of one another in each receptacle and rest on the'slanting bottom 1,

slides into the slot or chamber 1 so as-to lie opposite the needle 7 and to be stitched by it-to the fabric. Thus the inlay pieces, one by 011e, as the receptacles are swung downwardly, are fixed to the fabric and covered by fiat stitches by the needles, which in well knownmanner and through the medium of the jacquard mechanism are caused to perform their different. functions; stead of having the receptacles swing together with the levers, the same may be fixed and there may be meansto receive and convey the filling pieces from the receptacle into the range of the needles. finch construction is shown in Figs. 3, 3 and 4. Here the chute-like receptacles 1, are carried bya common stationary rail or bar 12, and their 14, guided on rods or pins 15. The transversal bars 2 connecting the levers 3, carry grippers 13, which are adapted, when swung from the position shown in Fig. 3 to the position shown in Fig. 3, to shift the slides 14 upwardly and to thereby open the bottom of the receptacles 1 The'inlay or filling pieces 1, which are stored in these receptacles on top of one another and normally rest on the slides 14, will then be permitted to slip out one by one onto the said grippers 13, which will be carriedwith the levers 3 downwardly into the range of the needles 7. Each of the grippers may be in the shape of a narrow, pan-shaped receptacle, which at one end is provided with a flange 13' adapted, when coming into contact with the slide 14, to shift the latter upwardly. In the center the said grippers are recessed as at 13 to allow the needles to stitch through the inlay pieces, held by the grippers. As the chamber 1 in the construction according to Fig. 1 or the parts 13 are open at the end which when swung downwardly would be down, means must be provided to hold the inlay pieces l from falling out.

According to the construction, Figs. 34, the inner surface of the part 13 is provided with prongs or tooth-shaped projections 16 which will grip the filling piece during the downward stroke of the parts 13 and re lease it when the parts 13 begin their upward or return stroke. a c

Any known means suitable for the purpose of holding the inlay piece in position in chamber or part 13 may be made use of and the same may vary according to the material used. I therefore do not Wish to restrict myself to any particular construction of such means.

Since the manner of conveying. the inlay But in-/ bottoms are'closed by slides pieces from the storage receptacle into the range of the needles, may also be varied without departing from the spirit of my invention, I do not wish to confine myself to the details herein shown and'described.

What I claim and desire to secure by Letters Patent is: In a acquard embroidering machine,

the combination with embroidering needles, of an inlay or filling feeding device, comprising storage receptacles for containing inIay or filling pieces and jacquard controlled means for conveying the said inlay piecesinto the range of the embroidering needles. j
